Liquid Crystal Display Technology. This invention addresses the challenge of efficiently displaying video content, particularly at the edges of display areas, within a liquid crystal display panel. The display panel includes a non-display area surrounding a central display area. The non-display area houses a system on chip (SoC). The display area is divided into at least two display sub-areas. Each display sub-area has its own timing controller. The SoC is connected to all timing controllers. The SoC sends edge video data, which is video content from the edge of an adjacent display sub-area, to the timing controller of a particular display sub-area. The timing controller receives and processes this edge video data. An adjacent display sub-area is one located next to the display sub-area associated with the timing controller. The edge area of an adjacent display sub-area is the portion of that adjacent sub-area that is closest to the display sub-area in question. The display panel operates with a frame period that includes a vertical active video interval and a vertical blanking interval. The vertical blanking interval is a period between scanning one frame and starting the next. The SoC transmits the edge video data to the timing controllers using a V-by-one interface specifically during this vertical blanking interval.
